Cement, or Portland cement, is a dry powder made from limestone and other materials. It is burned in a kiln and then ground finely. Cement reacts chemically with water to cause concrete to harden. There are several different types of Portland cement, designated as Type I, Type II, Type III, etc.

Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, marl, shale, iron ore, clay, and fly ash. The kiln resembles a large horizontal pipe with a diameter of 10 to 15 feet (3 to 4.1 meters) and a length of 300 feet (90 meters) or more. One end is raised slightly.

No. Our cement has been made easy to mix in the provided packaging without the need and extra cost of a separate mixer.

Yes, the Moon Bounce will be secured with sand bags rather than stakes. However it is HIGHLY recommended that the Moon Bounce be set up on grass whenever possible. It is possible that someone could slip getting into our out of the moon bounce and hit the ground. The cement is unforgiving when this happens. There is an additional fee for hard surface setups.

The Parallax Ez-Flow CDS is designed for the percutaneous injection of bone cement but have been optimized to work with the Parallax line of cement products. The Parallax IDS is designed for use with a proprietary cartridge cement-it will not work with vials or other types of formats.

Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.

No, Parallax cement delivery systems cannot be reused or resterilized and are to be disposed of after use.

If the cement sets too quickly that typically means it was mixed/injected at too high a temperature or too high a humidity. The cement is intended for use at 23 C (73 F)-cooler temperatures will lengthen the setting time while higher temperatures will quicken the set time.

This is a concrete question more than a radiant heating question. All concrete applications must be structurally satisfactory. There is no important difference between concrete mixes from the heating standpoint.

The amount of cement added varies typically from a range of 5% to 30%. There is no "cookbook" recipe. Quantity of cement to be added is determined through a treatability study and mix design conducted on the individual subject waste or medium. Treatability studies can be simple or more involved depending on the project requirements. A description of an involved treatability study written by the U.S. Army Corps of Engineers is found at: http://www.usace.army.

Cement coating is a colored concrete resurfacing material made of Portland Cement, Silica sand with some acrylic bonding agents.

Rapid Set cement in not a gypsum cement. Unlike gypsum, Rapid Set® cement can be used in wet environments.

It is recommended that you treat vinyl posts the same as you would wood posts. If it is common and normal to cement fence posts in your area, then you should cement the vinyl posts. [Return]

Every suite is sanitized daily with a high pressure hot water system. Cement floors not only stand up to this level of cleaning, they do not hold bacteria or other substances.

More than 5,000,000 barrels. The daily demand during construction of the dam was from 7,500 to 10,800 barrels. Reclamation had used only 5,862,000 barrels in its 27 years of construction activity preceding June 30, 1932.
